WASHINGTON -- While both presidential candidates enter the campaign's final week promising to be the better fiscal steward, each has outlined tax and spending proposals that would make annual budget deficits worse, analysts say, with Senator John McCain likely to create a deeper hole than Senator Barack Obama would.

Mr. McCain, the Republican nominee, has proposed bigger tax cuts. He has also promised more in spending cuts, but he has not specified where most of them would come from. Even now that the financial crisis has given rise to one bailout package and prompted both candidates to call for billions more in stimulus spending, Mr. McCain has stuck by his promise to balance the budget by the end of his term, a pledge that fiscal analysts call unachievable.
